Duty cycle calculation boost converter

WebDec 16, 2016 · Boost PFC converter circuit . The general goal of the boost PFC converter is to turn the switch (S 1) off and on rapidly and with a varying duty cycle in order to make the input current (i ac) sinusoidal and in phase with the input voltage (v ac). Boost PFC Converter Operation. The boost PFC circuit cycles rapidly between two states. Webvoltage Vo with the boost converter is necessary before operating it in a closed loop. Therefore, in this paper, a nearly accurate relationship for duty cycle is derived for a PWM DC–DC boost converter in terms of converter non-idealities, with which an engineer can get the information of maximum possible output voltage of the converter.
